Thls invention relates to new and useful improvements in emergency brake ap lying apparatus for cars upon railways an com= prises a simple and eiiicient apparatus of this nature so constructed that, in the event of a car leaving the track, automatic brake operating apparatus may be actuated.

My invention comprises a device of this nature having various details of construction, combinations and arrangements of parts-which will be hereinafter fully deaccompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure 1 1s a side elevation showing the.

application of my invention to a car. Fig. 2 is a transverse sectional'view through the car, giving a plan view of the apparatus, and Fig. 3 is a longitudinal sectional view on line 38 of Fig. 2.

Reference-now beinghad to the details of the drawings by letter, A designates acar, B the axle 'journaled therein and wheels upon the axle, said wheels loeing upon the tracks D. Pivotally connected at their up per ends to the pins E are the bars F which, at their lower ends, are pivotally connected to the ends of the bars H which in turn are pivotally mounted upon the bolts 1 mounted upon rollers Ti which have a rolling movement in elongated slots K formed in the car. lVashers K and K are mounted. upon said bolt and upon one of the washers K is. pivotally mounted a pawl L, shown clearly in Fig. 1 of the drawings, which is adapted to engagethe teeth of the rack bar N secured to the car helcw the slot K there- E in, there one of said ii. hare mount Specification of Letters Batent. pat t g y 212919150 Application filed October 14, 1914.

ed upon either side of the car, as shown in the plan view Fig. 2. The bars H have elongated slots H in their lower ends and in which the rollers O, journaled upon the rod 0', are positioned and in which slots H the rollers have a play. Washers and O are mounted upon the rod 0', one upon either side of the bar H, and serve to keep the rollers Q in proper position within said slots. Pivotal dogs are mounted one upon each washer and engage the rack teeth formed upon the face of the har H and serve to hold the valve lever T in different positions. A valve is mounted with in the casin T which is connected to the train pipe g and said valve is mounted upon a stem '1" to which an arm T is fastened and which is pivotally connected at R to a rod R which in turn is pivotally con nected to a pin R carried by the arms 3 of the block R, which latter is mounted upon the rod 0 and held thereon by means of a thumb screw R".

The operation of my invention will be readily understood and is as follows: When a train equipped with my emergency brake operating mechanism happens to leave the track and one of the rollers Q, or the pivotal ends of the rods F come in contact with either the track or the tie, an end thrust will air brake system, thusallowing the brakes,

not shown, to be applied. As the bar R is moved to close the valve, the bars H will also be moved and the pawls L, one on either side of the car, will move idly over the teeth of the rack loar N and thus hold the valve closed. After the 7 car has been replaced upon the tracks, the parts may be returned to their normal positions and again in readiness for operation in case of an emergencyl What I claim to be new is:

1. An emergency brake apparatus for cars comprising, in combination with a car, bars pivoted at their upper ends thereto, a rod connected at the lower end to said bars, a valve and pipe in which the same is mount ed, a stem to said valve, a crank to said stem, a link between said crank arm and rod, rack bars upon the car, bars pivoted to said rod, and pawls actuated thereby and adapt ed to engage the teeth of said rack hare,
